This is a GREAT pedal to drive you're already driven amp, just a little more. But for anything else i would not recommend it. Also there is a huge volume drop one the warm channel and too much volume at the hot side.
The warm channel has the most gain and not so much volume, also the tone knob doesn't really do anything. The drive knob on this channel has not a nice sweep, but has a lot to offer. Between 10 o'clock and 3 o'clock there is almost no difference in gain.
The hot channel is not really usable. It gives really much volume, a almost not usable low end en there is no gain on this channel. Well, there is a little, but only above 12 o'clock.
The pedal is really transparant which is great for a driven amp. But this is not a pedal for on top of a clean amp.
